What are some best practices for managing PHP extensions and dynamic loading in the php.ini file?

When managing PHP extensions and dynamic loading in the php.ini file, it is important to enable only the necessary extensions for your application to improve performance and security. You can do this by commenting out or removing unnecessary extension directives in the php.ini file and only enabling the extensions that your application requires. Additionally, you can use the "extension" directive to dynamically load extensions when needed.

; Disable unnecessary extensions
; extension=php_opcache.dll
; extension=php_mysql.dll

; Enable required extensions
extension=php_curl.dll
extension=php_mysqli.dll

; Dynamically load extensions
extension=php_gd2.dll
